Step 1: turn off the inside thermostat.

Step 2: Determine the low-pressure side of your car’s refrigerant and the suction size of the compressor. The suction valve for the compressor installs in the condensing unit. Connect the low-pressure side of the refrigerant to the suction side of the compressor.

Step 3: Using a wrench, close the service valve on the low-pressure side of the condensing unit. Depending on the kind of valve, you may need to use a hex key rather than a wrench to block the service valve.

Step 4: Slightly shut the high-pressure service valve. Make sure not to totally close the door. Allow the hex key to remaining in place.

Step 5: Using a low-voltage jumper, engage the compressor.

Step 6: Let the low-pressure valve drain.

Step 7: As soon as it reaches the vacuum, close the service valve.

Finally, turn off the compressor. Step 7 and the last step of de-energizing the compressor must be completed quickly since failure to do so may result in compressor damage. A faulty AC compressor would aggravate the difficulties with your vehicle’s air conditioning system. It is critical to have someone around to assist you with this removal procedure.
